Our Work

What is NCAP?

NCAP is the National Collection of Aerial Photography. It is one of the largest collections of aerial imagery in the world, containing tens of millions of aerial images featuring historic events and places around the world. It is the role of NCAP to collect and secure the future of these records, both digital and physical, to preserve them for generations to come, and to make them as accessible and available as possible. Based in Edinburgh, Scotland, our operational and development costs are funded through commercial enterprise.

Commercial Enterprise

The use of historical aerial photography by the European bomb disposal market forms the core of our current business. We supply the aerial imagery used to locate unexploded Second World War bombs and to identify contaminated land where development is being planned throughout much of Europe. We are increasingly diversifying our customer base beyond the risk management sector, beyond Europe, and to businesses working on environmental and land use change issues and to the media.

What We Hold

An internationally significant cultural asset, NCAP holds over 26 million aerial photographs covering places throughout the world. The vast majority of the photographs have been declassified and released by the United Kingdom Ministry of Defence and were taken during the Second World War and the Cold War. NCAP also holds the largest collection of both military declassified and non-military aerial photographs covering Scotland. Find out more about our Collections.

Who Are We?

The NCAP team have extensive experience of caring for historic aerial photography. Our backgrounds include digital imaging, geographic information systems, military imagery analysis, archive management, earth sciences, European history, town planning, record movement and photography. We are responsible for the long-term stewardship of the National Collection of Aerial Photography. We do this through record management, preservation, digitisation, cataloguing and research.

Records Management

The collection contains over 120,000 boxes of prints, photographic films and associated records housed in several locations. Each of these items has a unique barcode identifier which is linked to a database. This allows us to track the movement of individual items from their storage location to our public search room and imagery production facilities. We take great care to ensure that items are logged at each location so that we are able to find them again in an efficient manner. Find out more about record movement at NCAP.

Cataloguing

When we digitise images for our website, we create a geographic centre-point for that image, so that we can show its location on the surface of the earth. This work involves lengthy study of original sortie plots, which show where the aircraft flew during its reconnaissance mission, and the orientation of the digital images so that north is uppermost. The digitisation of images and finding aids for our website is funded by our subscribers.

Research

We carry out searches of our holdings on behalf of customers from around the world. This involves studying original sortie plots and microfilms to find and select imagery appropriate to the customer's needs. We also carry out extensive research in other archives to help find imagery in our uncatalogued holdings.

Legacy

NCAP is a living memorial to the military personnel involved in photographic reconnaissance and photographic intelligence work - in particular to the many reconnaissance pilots and aircrew who lost their lives. The imagery played a pivotal role in planning many of the key military operations of the twentieth century and provided information for UK Government foreign policy. In a wider sense, it has a significant memorial status given the many key moments in world history it records.

Regulations on the Re-use of Public Sector Information 2015

The European Union Regulations on the Re-use of Public Sector Information (2015) apply to information produced as part of the 'public task' of bodies throughout the UK public sector. The statement of 'public task' made by a public body is an important concept in the Regulations. It is one of the main factors determining whether information produced, collected or held by a public sector body falls within the scope of the Regulations. In the case of Historic Environment Scotland, the public task means the core role and functions of the organisation as detailed in the Historic Environment (Scotland) Act 2014.

The National Collection of Aerial Photography (NCAP) is an accumulation of aerial photography and associated records. On the basis that NCAP is considered a non-core activity for Historic Environment Scotland, one that does not receive public funding and operates as a commercial unit, and none of the aerial imagery held within NCAP was produced as part of the public task of Historic Environment Scotland or its predecessor bodies, the entirety of the NCAP holdings fall outwith the scope of the Regulations. This includes all the public records on deposit and all of the aerial imagery acquired from, and deposited by, third parties.
